You can't mix enlisted and brass too close you know -- the vapors from the enlisted men make 'em tarnish.

Time is of the essence here. You have approximately 15 minutes to abort
the missiles once you drop into the bathroom. Fight carefully but swiftly
through the hallways and by following your trusty objective marker. The
final two secrets of the game are in this stage.

Laptop 29 of 30 - Drop into the bathroom, exit the
hygiene facilities and turn left. Follow the hallway and mark your trail
with dead bodies. As you wander deeper into the base, there should be a
small meeting room on your left with the laptop. If you took the stairs
going down, you went too far ahead.

Locate the stairs (the Russian emblem motif is obvious) and head downstairs.
Hose badguys and waddle your ass over to the objective marker -- the launch
control room. Several knots of enemies bar your path.

You're probably wondering why there aren't any specific steps to going
about fighting, and the simple truth is you should fight using your common
sense. The result of every encounter in Call of Duty is randomized
and dependent on the A.I.'s reaction to your action (or reaction).

What you will want to know is that ammunition is moot at this point,
so you can splurge as much or as little as you want. The largest firefight
after the control room will be against a half dozen goons with no timer,
so you should splurge now and save your grenades and flashbangs for later
if you think you need them.

Your goal is to get to the slowly opening doors with about 10 minutes
or so left since the doors open slowly, and you need to spend time to place
and blow a C4 charge.

After the slowly opening doors, blast the rest of the bad guys, then
locate the short hall where your NPC allies go. Place the charge and step
back before blowing the wall. Both teams will blast the enemies inside
and you can enter the abort codes.

Laptop 30 of 30 - Once in the launch control room,
you can abort the launch first or grab the laptop. There's a small room
in the control room with the laptop sitting on the table. Cha-ching! Be
sure to try infinite ammo with the M16A4 Grenadier's grenade launcher.
Game-breaking.

Once the abort codes are entered, you leave through the elevator in
the control room. Head upstairs to the motor pool, kill the last few guys
and the mission ends.
